With the Deployment Workbench, you can add any Microsoft packages that you want to use. The most commonly added packages are language packs, and the Deployment Workbench Packages node works well for those packages. You also can add security and other updates this way. However, we generally recommend that you use Windows Server Update Services (WSUS) for operating system updates. The rare exceptions are critical hotfixes that aren't available via WSUS, packages for the boot image, or any other package that needs to be deployed before the WSUS update process starts.
